May 24, 2012 - By Christina George, Staff WriterThe Wyoming Highway Patrol reported Thursday morning that a driver fell asleep at the wheel, resulting in last week's one-vehicle rollover near Shoshoni that killed a woman and injured two children.
A news release issued by the agency states that Lehi L. Aoah, 18, of Fort Washakie, was westbound on U.S. Highway 20/26 in the early hours of May 18 when he apparently fell asleep, causing him to overcorrect and roll his two-door 2005 Pontiac Sunfire.
Also in the car were Aoah's sister, Jovan C. Willow, 24, and her daughters, Diamond Roy, 5, and Patricia Roy, 3. Willow died in the crash.
"The vehicle drifted across the center line going into the eastbound lane of travel," the release reads. "Aoah then overcorrected the vehicle's steering, and the vehicle rolled one complete time on the roadway."
The vehicle left the roadway on the north side, coming to rest on its roof.
The crash occurred at 4:06 a.m. on May 18 about six miles east of Shoshoni near milepost 94.
Aoah, who was wearing a seat belt, remained in the vehicle. Willow and her children, all not wearing seat belts or properly restrained, were ejected from the vehicle.
Willow was pronounced dead at the scene.
Aoah was transported to Riverton Memorial Hospital, and the children were taken by air ambulance to a hospital in Salt Lake City.
The Wyoming Highway Patrol lists Willow's residency as Fort Hall, Idaho, but Fremont County Coroner Ed McAuslan said she lived in Crowheart.
The family was reportedly returning home from a high school graduation in South Dakota.
"Upon completion of the crash investigation all documents concerning the investigation will be turned over to the Fremont County Attorney's Office for their review," the release states. "They will make the final determination of the filing of any charges as a result of this fatal crash."
Fremont County Attorney Brian Varn did not immediately respond to a request for comment.
